METHOD F MAKING SHINGLI: STRIPS.

Application led May 31,

j VBe it known that I, SAMUEL M. LANGS'rox, a citizen'of the 'United States, and resident off'lVenonah, in the county of Gloucester :ind State 'of New Jei'sey, liave invented certaiirncwand useful vImprovements in J`Methodsof Making Shingley Strips, of which fthe following isa specification.

@ rIhis invention relates to the manufacture 'ofthat- -typ'e'bf multiple shingle or roofing strip which is made of paper, felt, asbestos,

vor other'analogous flexible sheet`material satui'a'tedor treated with asphalt, tar, pitch -'oi" other waterproofing` composition and coated'on at least lone surface withl sand,

fgrit,`cruslied Slate, or other mineral or firc` 'proof material. y

f--A'comm`on form of such multiple shingle other end.

"isofa length' several times the width and fprovided' with a plurality of notches or recesses in one of the longer edges, so as ft form 'tabs each of a width corresponding {tthat -of anindividual shingle. l The strips i-'when-laid in overlappingrows on the roof ffliave the tabs and notches exposed at tht` lower edge to giveA the general appearance -of individual shingles with narrow spaces therebetween, as in the ordinary wooden 'shingle roof.

will'be formed between adjacent shingle tabs at the abuttingfends of two strips.

:The strips may be symmetrical and each `stripsy from sheet material which is continuously'orinterniittently fed from a i'oll. saturating and coating machine, or other `source 'of supply.

means of my linvention I produce rshingle'stripsof thesecond mentioned type` that is, non-symmetrical strips in which oncshingle simulating portion or tab has its side-edge in alignment with the end of the strip, and the strip has a full width notch or recess opening out at its opposite'end.

In carrying out my invention strips of this character are formed vby slotting or Patent No. 1,441,359, granted January 9 The notches shouldfbepositioned in each strip so that 'a notchof the proper width 1922. Serial No. 564,682.

perforatinv a sheet or blank-of a width substantially equal to a Amultiple of the y width of the finished strip, `and separately' cutting the rsheet transverselycand longitu dinally, vthe distance' between the transverse cuts being equal to the length of the finished 'strips andthe distance between the longitudinal cuts beineequal to thewidth= of the finished strips, the slots or perforations havin^- been so positioned as to form the slots or notches in said linislied strips. "The cutting ofthe sheet transversely vinto sections and theslitting of the separate sections loii- Y gitudiinally into v the strips, whereby the strips extend lengthwise of the sheet, has many advantages, as pointedl outin my 1923. Among these are the more rapid formation of the complete strips b`y reason ot the fewer transverse cuts; causing variation in the width of the sheet to appear in the strips as unobjectionable variations-'in strip width rather than objectionable vari ations in strip length, the avoiding of tabs or projecting shoulders -which-may catch on parts of the machine as the sheetadvances; and the more economical utilization of the sheet 'if the sheet be much Wider than the desiredlength of a strip.

From the standpoint'of simplicity of the machiiieit is important that the transverse cuts be along straight lines extending the full width' .of the sheet, whereby either a plurality of the finished strips are severed from the body of the slitted sheet by a single straight line cut, or the sheet is severed into sections which are later cut lengthwise into finished strips. I

The shingle strips as `laid in forininga roof, have the cndsof the tabs or individual shingle portions exposed, while the ,oppo- "site edge of cach strip is concealed beneath the strip or strips of the next row. As the original edges of the sheet are oftenso'niewhat irregular, it is desirable vthat` said original edges torni the non-slotted orconcealed edge of the strip rather thanlv theV edge of the strip formed by the ends of the tabs which are exposed in use, whereby all of the exposed edges -are accurately cut and uniformity and regularity of appearance is produced.

that the strfps all have their end recesses at the same end, in other words, the strips miV Y In layingthe root vit is also important cannot be properly assembled to produce uniformity of appearance il some have the end recesses at one end and some at the other.

The main object of my invention is to cut sheet material into non-symmetrical strips of the character above described, all of exactly the same shape with the strips extendi ing lengthwise of .the sheet, and with all of those of the strips which are exposed in use ,tormedby accurately positioned cuts, as distinguished from the. original edges of the sheet, and with all of the transverse cuts along 'straight lines extending the full lwidth of the sheet. I secure this object by a novel arrangement or piaci ing ol the slots or pertorations in the sheet whereby all ot'- the slots are. between and spaced from the side edges of the sheet, and each transverse cut coincides with oneb side edge ot' a slot in one row and with the oppo site side edge ot a slot Iin another row. Thus the strips which have'their slots openingr or facing toward one side edge of the Sheet have their end slots 'formed at the advancing end of the strips while the Strips which have their slots openingor facing toward the opposite side edge of the sheet have their end slots at the opposite end of the strips and all 'of the strips will be of the same' shape and size. 1

, So far as'N my present invention is concerned the sheet after being slot-ted or perforated may be slit into strips and there after these. strips cut` oli' transverselyfinto r sections, or the sheet may be out into sections and each section thereafter slitted lengthwise, or the slitting ofthe sheet into strips may be done before the slot-ting or perforating. Preferably I operate in accordance with the method claimed in my patent above referred to, and first form the slots or perforation's, then cutthe' sheet transversely into sections and thereafter slit or longitudinally cut each section into the Figs. 3, 4 and are plan views ol sections o'f a' sheet with other arrangements.

of the openings and cuts.

The material employed in carryingout my improved method may be that comn'ionly employed .n the manufacture of multiple shingles or roofing strips. This material is illustrated. as. a continuons sheet which may he delivered in the direction of thearrow from a roll or from a machine employedr trimmed oli" at the time the strips areseparated bythe longitudinal cuttingl apparatus.

As the first step in the cutting process there are formed a plurality of rows of transversely extendingr slots, the rows extending,- lengthwise of the sheet and the slots being uniformly spaced in all of the rows. The slots in one or more of the rows are'of- Set in the direction of the length of the Sheet `:trom the slots in the other rows and to anl extent equal to 'the .width of the Slot. AS'

shown in Fig. 2.; there are two rows of slots B, the slots of each rows-being in alignment transversely of the sheet withthose of the other row. There are also two rows of similar slots B. the slots of one row being in, alignment transversely of the sheet with the, slots of the other'row, but each of the slots B has one o'f its side edges in alignment transversely of the sheet with a similar edgey `of a slot B in the other row, and' with the opposite edges ot slots B in the two first mentioned rows. Thus, if the sheet be cut transversely on such a line vCC, the slots B will lie at one side ol the line and the slots B at the opposite side of the line, and all four slots will open out 'at .the resulting -cuttingedges.

The distance between thetransverse cuts may correspond t0 any desired number of individual shingle portions whichit is desired to include in an indi-y? vidual shingle strip. The sheet may be cut into sections. D hy the' transverse cuts each so positioned as to intersect all of the slots Va transverse row and coincide'with eine edge of one yor more of the slots, and ywith the opposite edge of the otherslotei lsaid row. The sections -D may -be the eafter slitted'or cnt lengthwise into.' the fin.' indi-- vidual shinple strips E. yThe longitudinal cuts are along lines which coincide 'with the ends of the slots in the several rows so as to form tabs or individual shingle'portions F with intervening .notches G opening vat but l one longitudinal edge ot the sheet.l It will be noted that each ystrip has :i tablor shingle portion li" which has its side edge in alignment with an end edge ot' the stripand has a notch G at the opposite end of the strip which opens out not 'only at the side of the sheet but at the end. By means of my arrangement oi slots ,each one of the strip-iff: E, which has the tahs l?" facing toward one original edge ot thel sheet, has its 'notch G at one end.` while each of the strips which have their tabs facing toward the opposite 12or y ,essjhereinat'ter claimed original edge of the sheet hasits notches G' at the `opposite end. Thus all of the strips arc exactly the same as tosize and shape.v

Aln Fig. :2 have shown an arrangement of strips whereby the two strips at one side of the center have theirtabs facing toward the vopposite original edge of the sheet, and those onthe other side of the center line extending `separates the two middle strips but does Inot register withthe slots in any of the rows.

ln Fig. le-.three strips face one vway Vand thet'ourth the oppositel way.

`li" the sheet be of' such width as to form only three strips, theseumay be arranged as shown in Fig. 5. while if the strip be of a width substantially equal to only two strips, then these strips might be arranged similar to the upper two in Figs. 3,` 4 or 5, or the middle two of Fig. 2.v A. l

The apparatus for carryingoutmy ,imn proved process forms no portion of my present invention. A form of apparatus which maybe employed for carrying out the 'procis disclosed and claimed in my cop/ending application, Serial .No 578,172, liled July 28th, 1922. -1n Fig.

1 l have shown diagramniatically the apparatus there claimed in which a .roller 10 has a series of longitudinally extending knives or cutters acting ragainst appropriate faces oni a roller 1,1 to form a series of transverse slits l-l corresponding to ,the side edges of the slots or Vopenings which are to he formed.`

The sheet, after passing between these rollers. passes between a second pair 12, 13, which act to form longitudinal slits K connecting the ends of the slits H of each pair to circuinscribe small waste portions which areremovcd on the roller 13 and taken from the latter by strippers 14. Thus the slots or openings B and B arevproduced. vThe sheet then passesl between feed rolls 15, 16, a traveling chopper or cut off mechanism including coacting knives 17 and 1S, then between feed rollers 19, 20, then rotary slitters shingle strips, each stripv vhaving a rowA of dinal slits being equal'ito the width 'of thel strip, the distance between ,the transverse cuts being equal tothe vlengjch-` of ytlle strip, each transverse .outy being straight and extending the 4fnll'widthr ofthesheet and the slots being so positioned transversely ofthe sheet 'that each slot has 'fone end registering with la lengthwise slitin the sheet and the slots being so ,positioned lengthwise of the sheet that one lor moreof the slots lie at' one side of and open into a transverse cutfand one `ormore other slots-lie at the" opposite side ofand open intoythesame transverse cut.
